BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in more detail based on examples.
FIG. 1 shows a first embodiment of an assembly member for a temporary structure. Specifically, the main parts of a column member 1 and a beam member 2 are shown.
[0011]
As shown in FIG. 1A, the column member 1 is configured by welding a connecting portion 4 in the middle of a round pipe 3. In the example shown in the figure, one connecting portion 4 is welded to the central portion in the longitudinal direction of the round pipe 3, but it goes without saying that two or more connecting portions 4 may be welded if necessary. It is.
[0012]
The connecting portion 4 is formed as a hollow regular octagonal column as a whole, and a regular octagonal top portion 5 and bottom portion 6 having an opening hole in the center, and a bent side portion 7 covering each side surface of the octagonal column are integrated. Is structured. In addition, the opening hole formed in the top part 5 and the bottom part 6 is the inside diameter substantially the same as the outer diameter dimension of the round pipe 3, and the connection part 4 and the round pipe 3 are welded in the upper and lower opening holes.
[0013]
The top part 5 and the bottom part 6 have a regular octagonal shape with one side having a length a, but two notched grooves 8 continuous to the side part 7 are formed on each side of the regular octagonal part at the top part 5. Yes. In addition, the length of the notch groove 8 of the top part 5 is set to L1, and the length of the notch groove 8 of the side part 7 is set to L2 (refer FIG. 2). The width of the notch groove 8 is W.
[0014]
As shown in FIG. 1 (b), the beam member 2 is configured by welding a locking member 10 to the inner surface of the end of a square pipe 9. The horizontal width a of the locking member 10 is substantially the same as the side a of the regular octagon of the connecting member 4. Further, the vertical height b of the square pipe 9 and the locking member 10 is substantially the same as the height b of the side portion 7 of the connecting member 4.
[0015]
As shown in FIG. 3, the locking member 10 is configured by integrating a flat plate-like main body 11 and two inverted L-shaped hooking pieces 12. Note that the hooking piece 12 is formed so as to protrude from a position at which the main body 11 is substantially divided into three equal parts. Of course, the positions of the two hooking pieces 12 coincide with the positions of the two notched grooves 8 formed on each side surface of the connecting portion 4.
[0016]
As shown in FIG. 2, the inverted L-shaped hook 12 includes a base end B that protrudes in the longitudinal direction of the square pipe 9 and an extension E that extends downward from the base end B. The shape and dimensions of the hooking portion 12 correspond to the notch groove 8 formed in the connecting portion 4, and the plate width of the hooking portion 12 is formed slightly thinner than the width W of the notch groove 8. Yes.
[0017]
Similarly, the length L1 ′ in the protruding direction of the base end portion B is formed to be approximately the same length as the length L1 of the notch groove 8 of the top portion 5. Further, the length L2 ′ in the vertical direction of the base end portion B is formed to be approximately the same length as the length L2 of the cutout groove 8 of the side portion 7. In addition, the part of the length L3 of the extension part E is a part which contacts the side part inner surface of the connection part 4, and implement | achieves the reliable connection of the column member 1 and the beam member 2. FIG.
[0018]
FIG. 4 illustrates the reinforcing member 20 used when it is desired to reinforce the connection strength between the column member 1 and the beam member 2. The reinforcing member 20 is formed by forming an extending portion 22 on the distal end side of a hollow rectangular column member 21, and the inner periphery thereof is formed slightly larger than the outer periphery of the square pipe 9.
[0019]
That is, the horizontal inner diameter a ′ of the reinforcing member 20 is slightly larger than the horizontal width a of the square pipe 9, and the vertical inner diameter b ′ is larger than the vertical height b of the square pipe 9 and the connecting portion 4. It is formed a little longer. Therefore, the reinforcing member 20 can be slid on the outer periphery of the square pipe 9. When the reinforcing member 20 is slid in the distal direction, the extending portion 22 sandwiches the connecting portion 4 from above and below, and the column member 1 and the beam member. The connection with 2 can be made more reliable.
[0020]
FIG. 5 illustrates an extension member 30 used when the column member 1 extends in the vertical direction. The extending member 30 is configured by integrating a disk portion 31 having an outer shape substantially equal to the outer shape of the round pipe 3 and a columnar portion 32 that penetrates the disk portion 31 and protrudes up and down. Here, the outer diameter φ of the projecting portion 32 is substantially equal to the inner diameter of the round pipe 3, and it is possible to reliably connect the column members 1 in the vertical direction.
[0021]
Then, the case where the framework of a temporary stage, a construction site scaffold, etc. is constructed | assembled using each member demonstrated above is demonstrated.
When constructing a temporary stage framework or the like, it is necessary to hang the beam member 2 between the adjacent column members 1 and 1 in a state where several column members 1 are erected. In such a case, the inverted L-shaped hooking piece 12 protruding from the beam member 2 may be inserted into the cutout groove 8 formed in the connecting member 4 from above. Unlike the conventional case, the connecting member 3 spreads outward in the radial direction of the round pipe 3, and it is only necessary to drop the hooking piece 12 into the notch groove 8 from above, so that the assembling work is extremely easy. is there.
[0022]
Further, since the connecting member 3 has an octagonal shape in plan view, the beam member 2 can be assembled to the column member 1 in any of the eight directions as shown in FIG. Any shape of stage or building can be accommodated. When it is desired to increase the assembly strength between the column member 1 and the beam member 2, the reinforcing member 20 is inserted into the square pipe 9 in advance, and the hooking piece 12 of the beam member 2 is connected to the connection member 4. After dropping into the notch groove 8, the reinforcing member 20 may be slid and the connecting portion 4 may be sandwiched from above and below by the extended portion 22.
[0023]
If the column member 1 and the beam member 2 are assembled in this way, and a board material or the like is laid on the horizontal plane formed by the beam member 2, a temporary stage and a construction scaffold can be completed. At this time, since the upper surfaces of the connecting member 4 and the beam member 2 are flush with each other, the board member can be supported by the connecting member 4 and the beam member 2. In addition, what is necessary is just to connect the column member 1 continuously using the extending member 30 shown in FIG.
[0024]
FIG. 7 shows a second embodiment of the assembly member for the temporary structure. Specifically, the main parts of the column member 31 and the beam member 32 are shown.
In the column member 31 of the second embodiment, the overall shape of the connecting member 34 is slightly different from that of the first embodiment, and the top portion 35 and the bottom portion 36 are welded at positions that enter the inside from the upper and lower end surfaces of the side portion 37, respectively. ing. Therefore, in this connection member 34, the welding operation of the side portion 37, the top portion 35, and the bottom portion 36 is easier than in the case of the first embodiment.
[0025]
The beam member 32 of the second embodiment is also characterized by the shape of the locking member 40. That is, as in the case of the first embodiment, a simple plate member is not welded to the square pipe 39, but a bent locking member 40 as shown in FIG. 8A is inserted into the square pipe 39. ing. A notch C is formed in a part of the upper and lower end faces of the locking member 40, and the square pipe 39 is caulked from above and below according to the position of the notch C with the locking member 40 inserted. The retaining member 40 is held inside the square pipe 39.
[0026]
FIG. 9 illustrates a reinforcing member 50 according to the second embodiment. The reinforcing member 50 is formed by integrating two plate members 51, 51 formed bent as shown in the figure with bolts 52 and nuts 53. In addition, two bolt holes are provided on each of the upper and lower sides, and the second hole is used as a bolt hole for holding a streak 55.
[0027]
